SUSPENSION FOR ELECTRIC RAILWAY MOTORS.

Application filed July 6,

This invention relates to suspensions for electric railway motors andpertains particularly to a-suspension for an electric railway motorwhich is mounted 'on the axle of the truck. According to the inventionit is proposed to mount two, housings in spaced relation to one anotherupon one'end of a motor which is mounted upon the axle of the truck.

'. Within the housings are disposed blocks of yielding non-metallicmaterial adapted vto receive the ends of a leaf spring which is rigidlyattached at its mid-point to the bolster transom of the truck. Thus,startingand stopping torques of the motor are yieldingly resisted andthe necessary torque reaction for the motor is provided.

- For a better understandin of the invention reference is to be had tothe ollowing detailed accompanying mounted upon the axle b of the truck.To the nose of the motor a are bolted housings a a within which aredisposed blocks of yielding non-metallic material, as a.

of a leaf spring 0, 'rigidly'attached to the bolster transom of thetruck by means of the bracket 0' and the clamp 0 riveted thereto aredisposed within the blocks of yielding nonmetallic material as at c.

It will be seen that the unbalanced weight of the nose of the motor issupported by the The ends 1927. Serial No. 203,717.

spring 0 through the blocks of yieldin nenmetallic material and thatstarting an stopping torques are yieldingly resisted thereby, beingtransmitted with diminished intensity to the bolster transom. of thetruck; The necessary torque reaction for the motor is provided bythe'spring and transmitted to the bolster transom.

' Obviously, the spring a might be rigidly attached to the motorby'means of the clamp c and the housings a", (1 attached to the bolstertransom of the truck. This and other changes inthe relative dispositionof parts will readily suggest themselves and no limitation is intendedexcept as indicated in the following claims. 1

What I claim is:

'1. In combination with a railway truck, a

motor mounted on the axle, housings mounted upon the nose of the motor,blocks of yielding nonmetallic material disposed within the housings,and a leaf spring carried rigidly with the bolster transom of thetruck'and hav-. ing its ends disposed within the blocks of yieldingnon-metallic material,

2. In combination with a wheeled vehicle, a motor mounted on the axle,torque reaction means interposed operatively between the motor and theframe and comprising housings carried with one of the last namedmembers, yielding non-metallic material disposed within the housings,and a leaf spring carried with the other of said last named members andhaving its ends disposed. within said yielding non-metallic material.
